Team for WTC 'Bird of Peace' Tries to Remain Unflappable
...projects trail the hub in development. The interdependencies make it difficult to change any element without creating consequences almost everywhere else, says Calatrava, who is DDP’s design architect-structural engineer.
Organization of DDP’s full-service team is almost as convoluted as the hub’s space plan. There are 180 full-time employees, including 120 from 40 subconsultants. Most work out of a job office just blocks from Ground Zero.
